Ob leeg S460N thiab S460NL muaj qhov zoo - cov qauv nplej thiab 460 MPa yield zog, tab sis S460N raug kuaj rau -20℃toughness, thaum S460NL excels ntawm -50 degree, ua rau nws zoo tagnrho rau cov huab cua txias. Raws li ib feem ntawm en 10025 3 normalized steel phaj tsev neeg, ob qib yog normalized rau kev ua tau zoo ib yam.
S460N (EN 10025-3): Raws li ib txwm ua los yog ua tau zoo dov, nrog 460 MPa tawm los lub zog thiab -20℃toughness, zoo tagnrho rau cov choj thiab cranes nyob rau hauv nruab nrab climates (xws li, temperate Europe).
S460NL (EN 10025-3): Raws li ib txwm ua los yog ua tau zoo dov, nrog 460 MPa yield zog thiab -50℃toughness, haum rau cov huab cua txias (xws li, Arctic cheeb tsam lossis sab qaum teb Europe).
Ob qib sib koom ua haujlwm zoo sib xws tab sis sib txawv hauv qhov qis -kev ua haujlwm kub, nrog S460NL muab qhov zoo tshaj plaws rau cov mob hnyav.

Processing thiab Fabrication
S460N: Normalized for consistent microstructure; suited for standard welding and machining. Preheating (100-150°C) for >20 hli; PWHT yeem (550-650 degree).
S460NL: Normalized nrog stricter impurity tswj rau txhim kho toughness; zoo sib xws welding xav tau.
Consumables: Ob leeg siv ER70S-6 (GMAW), EM12K flux nrog EH14 hlau (SAW). S460NL qhov qis impurities txo qhov tsis zoo ntawm cov vuam.
Daim ntawv thov
S460N: Cov choj, cranes, thiab lub hauv paus ua haujlwm nyob rau hauv cov huab cua nruab nrab (xws li, temperate regions).
S460NL: Offshore platforms, cua yees, thiab txuas hniav nyob rau hauv cov huab cua txias (xws li, Arctic los yog sab qaum teb Europe) vim muaj superior low -kub toughness.
S460NL zoo dua rau sub-zero tej yam kev mob, thaum S460N haum rau ib puag ncig me me.
